IMPROVEMENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 56,743, dated July 31, 1866.

`.To all whom it may concern: 4

Be it known that I, ALEX. GORDON, of Rochester, in the county of Monroe and State of New York, have invented a new and useful improvement in the manner of supporting the adjustable feedroller of feed-cutters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a vertical section ot' afeed-cutter having my invention attached. Fig. 2 is an inverted plan of the yoke y and spring s.

Like letters indicate corresponding part's.

rlhis invention relates to that class of feedcutters having an upward cut, and in which the lower feed-roller'is made the adjustable one laterally 5 vand it consists in pivoting the parallel yoke, to which that roller is attached, by pivoted rods, to the frame at a point intermediately between 'the front and rear end of the said yoke, and applying the counteracting spring to the cross-bar at the rear end of the yoke.

To enable others to make and use my invention, I will describe its construction and operation.

I use in this machine the same cutting apparatus which was presented in my former application7 patented February 17, 1863, the knife or knives being attached to revolving heads h in such a manner as to produce an upward shearing stroke across the face of the throat-bar b.' The feed-rollers R are also arranged, geared, and operated the same as formerly; but the parallel yoke y, which supports the under or variable feed-roller, instead of having the rear end pivoted to the frame, as heretofore, and the spring s extended to the front bar, a, the yoke is pivotedy to the frame at an intermediate point ,between the front and rear, and the end of the spring s rests upon the rear bar, c, of the yoke.

It Will be seen that by'this arrangement of porting-bars r are hinged, for the purpose set` forth, the parts acting conjointly, in combination with the upward cut.

ALEX. GORDON.
